The Small Craft Advisory issued by the National Weather Service has been extended through 6 a.m. Friday for Big Island southeast and leeward waters along with the Alenuihaha channel. Rough seas of 8 to 13 feet are expected.
**Click directly on the images below to make them larger. Charts include: Big Island projected winds, tides, swell direction & period and expected wave heights.**
Hilo side: NW still wrapping into select spots on the Hilo side. As the swell continues to fade, surf is expected about head high to overhead or possibly more at the best breaks exposed to the swell.
Kona side: Surf is expected knee to maybe chest high for the best exposures.
South: Southeast shores open to the trade swell could see waves knee to chest high, though a slight chop is expected. Minimal surf out of the southern hemisphere – knee high or less.
Our current northwest swell (305°-345°) will continue to fade. The Kona side continues to be heavily shadowed from this swell.
A series of swells are expected over the weekend and into next week as well. Next on tap a west-northwest for Saturday / Sunday. This swell is expected to peak overnight Saturday into Sunday with double overhead surf on the sets. The Kona side is forecasted to get some shoulder high waves from this swell before it swings more north on Sunday and due north on Monday.
Another set of northwest swells are expected for the second half of next week with yet another large northwest swell due for next weekend. All dependent on how the storms actually end up developing. Will keep an eye on it.
An out of season south swell is expected late in the weekend into early next week. We could see a fun little boost up to head high at the best breaks.
Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
